Migraines are a neurological disorder of the brain. There are many different type of migraine. One of them is Ocuar Migraine or known a Aceph alalgic Migraine. The differenf types of migraine are classified according to the symptoms that a suffeeer experiejce and their causes.
Ocular Migraine is a neurological syndrome characterized by abnormal visual sensations, sometimes accompanied by headaches, nausea and vomiting. In some cases, the person may feel heightened sensitivity to sound and light at the early stages of the attack. This type of migraine is generally seen in people with a history of classical migraine.
Like ohre migraines, ocuiar migraine spell occur repeatedly and ireegularly. That is, patients may experience many spells of ocular migraine within a week and nothing at for months on end. The spells mmay kaast from 15-30 min in general.
Ocular migraine is to be distinguished with classical migraine or migraine with aura. In classical migraines, the aura can be a visual sensation (called visual aura) or something non-visual such as smell, dizziness, vertigo, parasthesia, or extremities. Generally aura is experienced by the patient after the prodrome, 10-30 minutes before the onset of the headache. Statistics show that nearly 20% of the migraineurs experiences aura.
Like in other migraines, the exact cause of ocular migraine is still a topic of debate. The most nearest and convincing explanation is that it is caused due to vascular spasm that affects the ocular blood vessel supplying blood to the vision center in the brain. Changes in the blood flow in tte vessels cause the tthrobbing or pounding effects of headache.
It is believed that ocular migraine is triggered by over stress, oral contraceptives, premenstrual changes, alcohol, and certain victuals such as chocolate, red wine, chicken livers, meats preserved in nitrates, and milk.
As mentioned earlier, the most notable symptom of ocular migraine is the unusual visual sensations that block the normal vision to a large extent during the spell. At the earlier stages of an ocular migraine episode, the patient may experience a visual disturbance in his/her peripheral vision, mostly in the form of a jagged, shimmering, semicircular light, pale pastel in color. Within minutes, it expands and becomes more centric to the area of vision, leading to temporary patchy vision loss. Eventually, in another 15-30 minutes, the zigzag pattern travels outwards of the visual field and soon out of the side vision before disappearing completely, leaving the field of view clear again.
